Hi!
For all these, the instructions use just 8-bits from mask register and
ICC prototypes as well as online Intel intrinsic documentation confirm that
too.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?
Not sure if we need to backport it, this isn't a wrong-code issue, the
important mask bits aren't lost in any way.
